Since there is a new version available (1.6.6) i will be making a new U3 release for that version.

It's still in progress and i will inform you as soon as it is ready.
Once i have an easier way to make the u3 compatible with newer versions without building a whole new u3 package i will be posting the details here.

Hopefully that way the u3 installer will be compatible with newer versions without messing up the previous install. (1 U3 installer for all versions to come )

What i had to do to make it work, was take the portable launcher and convert it to U3.
Also needed to make some changes in the way it launches Xampp control center to make it compatible with new releases and offcourse older versions.

I have tested the U3 launcher on various versions of xampp and it works !
Simply download the zip archive of xampp (full or lite (compatible with both)) and unzip it into the root folder of your usb drive.
Install the U3 Webserver launcher on your U3 usb stick and you're ready to go !
